Small round water jacket furnace for silver-lead ore . A water jacket furnace could be used to reduce non-ferrous oxide ores mixed with coke, to produce metal, but its main use was smelting the more common sulphide ores. The feedstock was the ore, coke and fluxes. When smelting lead sulphide ores, a water jacket furnace produces molten lead and ...
Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores.Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials.

Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...
After thickening, slurry is often stored in ponds or impoundments. Alternatively, it can pumped into a belt press or membrane filter press to recycle process water and create stackable, dry filter cake, or "tailings". [20] Thermal drying is usually used for fine particles and to remove low water content in the particles.
Froth flotation to separate plastics, Argonne National Laboratory Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity.
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders. PM processes are sometimes used to reduce or eliminate the need for subtractive processes in manufacturing, lowering material losses and reducing the cost of the final product. [ 1 ]
Non-ferrous extractive metallurgy is one of the two branches of extractive metallurgy which pertains to the processes of reducing valuable, non-iron metals from ores or raw material. [ 1 ] [ 2 ] [ 3 ] Metals like zinc , copper , lead , aluminium as well as rare and noble metals are of particular interest in this field, [ 1 ] while the more ...
